Edward De Bono made a clear distinction between intelligence and thinking. He said that they are not the same and compared them to a car and a driver. Intelligence is the car and refers to your DNA potential. Thinking is the driver of this car.

The key insight of this comparison is that no matter how “good” the car is if we have inadequate thinking skills, it is impossible to utilize the car to its best performance. In fact, our inborn intelligence is far less important than our ability to acquire excellent thinking skills.

In recent neuroscience research, a prediction was even made that in future that quality thinking skills may even become more important than a university degree. So, each of us needs to ensure that we deliberately working towards discovering how they think, measuring the quality thereof and increasing our competency.
Of course, it consists of the necessary brain rewiring effort and making use of possible assistance by others, but it can be done!
